WASHER FOR AXLES.

Specification of Letters Patent No. 13,327, dated July 24, 1855.

To all whom it may concern:

Be it known that I, ALFRED E. SMITH, of Bronxville, WVestchester county, and State of New York, have invented a new and useful Improvement in Packing-WVashers for Carriage and other Axles, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification,

in which- Figure 1, is a face view of the said improved washer; and Fig. 2, a cross section thereof.

The same letters indicate like parts in all the figures.

My invention consists in making packing washers for axles of leather or other equivalent fiexible and yielding material, with blocks of metal or other equivalent hard sub stance inserted through the substance of the washer to prevent the rapid wearing away of the leather.

In the accompanying drawings a represents an annulus of leather such as is commonly used on the axles of carriages at the end or ends ofthe box. Such packing washers, as heretofore made of leather alone, wear away very soon on the two faces and become so thin that they have to be removed. To prevent this too rapid wearing away of the leather I insert through the thickness of the leather copper rivets b, b, 6 three in number, more or less, and hammer them down so that they shall present a thickness slightly less than the thickness of the leather, so that when the leather is slightly compressed between the shoulders of the axle or journal and box the said metallic shoulders shall run in contact with the ends of the rivets, and thus prevent the too rapid wearing away of the leather surfaces, such as would take place if not protected by the metal rivets.

It will be obvious from the foregoing that instead of the copper rivets above specified other metals or hard wood may be substituted. And although I prefer to secure the blocks in the leather as described they may be inserted without riveting. And it will also be obvious that other substances such as gutta percha may be substituted for the leather.

WVhat I claim as rny-invention and desire to secure by Letters Patent is Inserting blocks of metal or other equivalent hard substance in packing Washers made of leather or other equivalent flexible and yielding substances, substantially as and for the purpose specified.
